LOOM-SHUTTLE SPECIFICATION forming part of Letters Patent No. 344,369,dated June 29, 1886.

Application filedDecembcrl2,1884. Serial No.1.30,171. (No model.)

To all whom it may concern:

Be it known that I, LOUIS GoDDU, of Winchester, county of Middlesex,State of Massachusett-s, have invented an Improvement in Loom-Shuttles,of which the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

My invention is embodied in a shuttle of the class known asself-threading, and it consists, more especially, of improvements in thetension-regulating mechanism for the thread, and in the device forguiding and delivering the thread from the shuttle, as will bedescribed, and specifically pointed out in the claims.

Figure 1 is a top view of a shuttle embody ing my invention; Fig. 2, aside View thereof; Fig. 3, a top View and side elevation of the platecontaining the drawing-off post and the delivery-eye, and Fig. 4 similarviews of the movable member of thetension-regulatingdevlce.

The body A of the shuttle, spindle B, and spring 0 are and may be asusual. The shuttle-body, in front of the spindle-point, is cut away toreceive the plate a, which, as shown, has integral with it thedrawing-oft post b, the thread-delivery eye 0, and the guard (Z. Theside wall of the shuttle, as best shown in Fig. 2, is bored to receivethe delivery-eye c, and a diagonal slot, 2, is cut from the top edge ofthe shuttle-wall downwardly and forwardly into the hole for the eye, tothus permit the shut tle-thread to be inserted laterally into the saidhole and into the delivery-eye 0 through the open space 8, the said eyeforming a metal lining for the hole in the shuttle-body, the open part 3of the eye coinciding, substantially, with or being in communicationwith the diagonal slot 2 in the shuttle-body.

I do not herein claim the shuttlespindle and the shuttle-bod y providedwith a thread opening or eye, and slotted diagonally to intersect thesaid opening, and a drawing-off hook or stud located substantially inline with the longitudinal center of the spindle, combined with aslotted guideeye arranged in the said open ing to receive theshuttle-thread led into the said slot, the same forming thesubject-matter of my application No. 116,383, filed January 3, 1884. Theguard d rests against the inner wall of the shuttle-body, at one side ofthe hole referred to, as in Fig. 1, and serves as a guard against whichthe shuttle or filling thread t bears, thus obviating the cutting of thethread into the wood. The post h is bent up from the plate asubstantially in line with the axis of the spindle B, and the threadpasses from the cop, or it may be bobbin, about the post preparatory toleaving the shuttle, the thread being drawn from the cop or bobbin aboutthe said post. The post is made hook shape, to form a space to receivethe thread and retain it substantially in line with the axis of thespindle; and to facilitate the introduction of the thread into thehooked part of the said post I have extended the point 4 of the postforward and upward into a chamber or space formed in the body of theshuttle near its point, the free end of the said point terminatingin adepression or countersink, 5, made in the top side of the shuttle-body,aslot, 6, leading from the said depression into the open central spaceof the shuttle-body, where is located the main part of the plate a. Aloop of thread, i, laid in the depression 5 may be caught under thepoint 4 of the post, and, by means of the slot 6, the thread may bereadily introduced into the hook of the post. The part of the postagainst which the thread It bears as it is drawn from the shuttle inweaving may be more or less rounded and of greater or less width.

To vary the extent of the tension on the thread t, I have provided theshuttle with a movable plate, f, provided with a slotted or open eye, 7,formed, preferably, integral with the said plate, and I have providedthe platef with a hole to receive the same screw, 9, which is employedto hold the plate (6 in place, the metal about the hole in the platefbeing struck up to form. a conical teat, 12, to enter a conicaldepression, 9, in the plate a, the said teat entering the saiddepression, and serving as a center for the plate f on the plate a.Adjustment of the eye-like end 7 of the platefin the are of a circle,which, it will be obvious, is admissible, owing to the construction ofthe parts as described, enables the shuttle or filling thread to befolded more or less about the post I). The more the thread is bent aboutthe edge of the said post the greater the tension, and vice versa, andconsequently by the ad justment of the plate f about its center thetension on the threadtmay be modified as desired.

The shoulder or lug 15 on the plate f serves l combined with the platea, provided with the 20 to determine its extreme position.

I claim- 1. The plate a, having integral with it the thread-delivery eye0, the guard d, and the drawing-01f post I), the latter having theextension 4, combined with the shuttle-body having the chamber 5 andchannel 6 and the delivery opening or eye, substantially as and for thepurpose described.

2. The shuttle-body provided with a hole at one side and slitted at 2,to intersect said hole,

connected open delivery-eye, which serves as a lining for the said hole,and having athreadpost, I), provided with a hook, as shown anddescribed.

3. The shuttle-body provided with a hole at 1 one side and slitted at 2,to intersect said hole,

connected open delivery-eye, which serves as a lining for the said hole,having a threadpost,'b, provided with a hook, and a guard, d, as shownand described.

4. The plate a, provided with the hooked post, combined with theshuttle-body having a depression, 5, and a slot, 6, whereby theshuttle-thread may be inserted into the hook of the post, and theadjustable tension-plate f, provided with an eye, 7, to operatesubstantially as described.

combined with the plate a, provided with the I to this specification inthe presence of two subscribing witnesses.

In testimony whereof I have signed my name LOUIS GODDU.
